The transmission rod is used to drive the turnover part to switch between the horizontal state or the vertical state.

A vacuum sucker is installed on a robotic arm to suck an object. The robotic arm includes a body and a tip axis. The tip axis is disposed with an adapter plate. The vacuum sucker includes a housing, an actuator, and a flexible suction cup. The actuator passes through the housing and includes a main part, a thrust rod, and an elastic element. The main part has a first end and a hollow slot. The flexible suction cup is sleeved on the first end and is formed with an air chamber. When the thrust rod is located at the first position, the air chamber and the hollow slot are not intercommunicated with each other. When the thrust rod is driven by the adapter plate to move to a second position, the air chamber and the hollow slot are intercommunicated with each other.

An anchor assembly (A) for hollow walls comprises an anchor body (400) and a toggle member (231) that is displaceable between a first position wherein the toggle member (231) is substantially aligned with the anchor body (400) such that the anchor assembly (A) can be inserted in the wall (W) via a cutting distal end (325) of the toggle member (231), and a second position wherein the toggle member (231) extends behind the wall (W) at an angle relative to the anchor body (400) which extends through the wall (W). The toggle member (231) is held captive in the first position but is released and then rotated to the second position by a fastener (218) introduced in the anchor body (400). The fastener (218) threadably engages the toggle member (231) thereby drawing the toggle member (231) against a hidden side of the wall (W).

A fastener for securing a first object to a second object includes a push member, a rigid shaft, an engaging member, a biasing member, and an anchor. The push member and the anchor are fixed to opposite ends of the rigid shaft. The engaging member is slideably coupled to the rigid shaft between the push member and the anchor. The biasing member is disposed between the push member and the engaging member to urge the engaging member toward the anchor. In a particular embodiment, the anchor is deployable.

A fixing device 101 has a pair of complementary fingers 102,103 complementary pivot formations 121,122. Each has distal portion 104 and a proximal portion 105. Both have a flat surface 106, which abuts the same face in the other finger, both at the distal portions when the fixing is arranged for insertion in an aperture 107 in a board 108 and at the proximal portions when the fingers are arranged both for insertion and gripping of the board.

The distal portions each have a surface 111 with an edge 1112 common with the surface 106. This surface 111 comes into abutment with the back face 112 of the board 108. The proximal portion is generally hemispherical to allow rotation within the aperture 107. A lug portion 1161 generally in the direction of the distal portion 104.

Both have a flat surface 106, which abuts the same face in the other finger, both at the distal portions when the fixing is arranged for insertion in an aperture 107 in a board 108 and at the proximal portions when the fingers are arranged both for insertion and gripping of the board. The distal portions each have a surface 111 with an edge 1112 common with the surface 106. This surface 111 comes into abutment with the back face 112 of the board 108. The proximal portion is generally hemispherical to allow rotation within the aperture 107. A lug portion 1161 generally in the direction of the distal portion 104. With the fingers engaged and their distal portions brought as close to alignment as possible, the Tee projections 114 abut the flanges 109 at angled faces 135. The contours of the fingers are such that they can be inserted into the aperture 107 until the distal portions 104 enter the aperture.

Passage of these through the aperture is inhibited by the lugs 1161, specifically by abutment of the angled back surface 118. Pressure on the angular relief surfaces 120 of the abutments 1162 urges the lugs into the front face 135 of the board 108. The reaction of the board acts about the pivot centrally of the aperture, tending to turn the fingers about the lugs under the constraint that they are pivoted together. The fingers are turned with the distal portions coming to lie on the backside of the board. Th

An anchoring device for insertion in a hole provided in a structure such as a wall (hollow or solid) comprises proximal and distal sections. The proximal section includes a head defining an aperture for receiving a fastener, and the distal section includes a pair of expandable wings displaceable between collapsed and expanded positions. Each wing is biased towards its expanded position such that the wings can engage the structural material delimiting the hole or a distal surface of the structure. The distal section comprises, proximally of the wings, a variable-length flexible portion for allowing the wings to engage the distal surface of the structure for various structure thicknesses. The distal section comprises, distally of the wings, a tip section adapted to spread outwardly when engaged by the fastener. The proximal section comprises a pair of legs each having a toothed rack for engaging the structural material.

An example pivot nut assembly includes a pivot body and a nut. The nut is pivotably engaged in the pivot body.

A blind fastener may include a bolt. The bolt includes a head, a shank coupled to the head, and a number of external threads formed on the shank. The blind fastener may also include a mount coupled to the bolt, and a fastening block coupled to the mount. The mount may include a body, at least one arm extending from the body, and at least one pivot mount formed on and extending from the arm about which the fastening block pivots.

A toggle fastener includes an arm extending along a first axis and defining a threaded opening through the arm along a direction perpendicular to the first axis the toggle fastener. A rachet strap extends along a second axis and is pivotally coupled to the arm adjacent a proximal end of the rachet strap. The arm and rachet strap cooperate to block the arm and rachet strap from aligning. Pivoting the arm and the rachet strap relative to each other about a first direction, the angle between the first and second axes can be reduced to a first angle before further pivoting is blocked in a first blocking configuration of the toggle fastener. Attempting to pivot the rachet strap further in the first direction relative to the arm causes the rachet strap to recoverably flex.

An anchor assembly includes an anchor body for insertion into a wall. A toggle member has an aperture therethrough and is slidable and pivotable relative to the anchor body. The toggle member is configured to have a first position slid forward aligned longitudinally with the anchor body, a second position slid forward and pivoted relative to the anchor body when the fastener engages the toggle member pivoting it relative to the anchor body, and a third position slid rearward and pivoted relative to the anchor body when the fastener enters the toggle member aperture and drives the toggle member rearward to engage the toggle member with the anchor body.
