A transmission actuator unit (131) configured by combination of a selecting actuator (133) and a shifting actuator (134) is mounted on an upper surface of a connection box unit (101). A connection box frame (102) is slidably supported along guide rails (20) between a pair of main beams (15a) of a slanting frame (11). By sliding the connection box unit (101), it is possible to adjust a height position of the transmission actuator unit (131) to a height position of a shift lever.

The building of systems on breadboards such as optomechanical systems using reference stop assemblies is presented. Each reference stop assembly has a threaded base engageable with the breadboard to removably mount the reference stop assembly thereto, a support shaft connected to the threaded base and a reference ball. The reference ball is captively mounted to the support shaft and has a translational play in a plane perpendicular to the support shaft. The reference stop assembly also includes a clamping member mounted to the support shaft over the reference ball. The reference stop assembly is configured such that, when the reference stop assembly is mounted to said breadboard, the support shaft projects normally to the mounting surface of the breadboard and the clamping member cooperates with the breadboard so as to apply a clamping force to clamp the reference ball against a circular seat of a mounting hole on the breadboard.

A large boom stand having a base with adjustable wheels that can vary the foot print size of the boom stand. The boom stand allows for height changes using pneumatically assisted lifting mechanisms that facilitate the raising and lowering of the boom arm when carrying a heavy load.

An assembly includes a series of support structures. Each of the support structures includes a base, a top plate having a continuous surface area, and a connector coupling the base to the top plate. The connector assumes a compressed position when under load from an object. The support structures that are in an extended position provide a lateral retention force to the object.

The present disclosure provides a selfie device, including a telescopic rod (8), a longitudinal handle (6) sleeved on the telescopic rod (8), and a clamping device (5) rotatably connected to a top end of the telescopic rod (8). The clamping device (5) includes a vertical arm (59), at least one base (58) having a bearing function and disposed on a lower end of the vertical arm (59), a connection head (588) connected to the at least one base (58) and configured to be rotatably connected with the telescopic rod (8), and two transverse clamping arms (57) respectively and rotatably disposed on two sides of the vertical arm (59) and configured to transversely clam. And at least one of the two transverse clamping arms (57) is stretchable.

A workcell comprises a base structure, a column having a lower part connected to the base structure and an upper part which is height-adjustable relative to the lower part. A first and a second support structure are mechanically connected to the upper part of the column via a first and a second joint element to allow axial rotation of the support structures around the column. At least one of the joint elements comprises a latching mechanism configured to block movement of the joint element with respect to the column in a normal state and to release movement of the joint element during an adjustment operation initiated by a user of the workcell.

Disclosed is a console bed mechanism to provide access to controls on console bed transported in a transport case. The console bed mechanism may include a base plate positioned in the transport case and comprising a bearing, an upper plate secured to the console bed and connected via the bearing to the base plate, a rotation arm having a lower end mounted to the base plate and an upper end mounted to the upper plate, the rotation arm configured to rotate the console bed between: a transport position in which the console bed is at least partially in the transport case, and an operation position in which the console bed is at least partially above the transport case and is positioned to be operated, and also including an elevation arm that raises the console bed and having a lower end mounted to the transport case and an upper end secured to the base plate.

A hamster running wheel and an axial connection device for a hamster running wheel are provided. The hamster running wheel includes a support frame (2) and a running wheel body (1) supported on the support frame (2) through a rotating mechanism (3). The rotating mechanism (3) includes an axial mechanism (32) and a plurality of bearings (33). The plurality of the bearings (33) are stacked to form a bearing set, and are arranged in series on the axial mechanism (32). The inner rings of the plurality of the bearings are fixedly connected to the axial mechanism (32), and the outer rings of the plurality of the bearings are fixedly connected to the running wheel body.

A support device for a tire sealant inflator contains: a C-shaped rib on which two spaced plates are engaged when inflating and supplying sealant into a broken tire, and the tire sealant inflator and the support device are connected so as to exert the tire sealant inflator stably. The support device further contains a base, and the base includes a C-shaped holder formed thereon, an opening defined on a side of the C-shaped holder, and the C-shaped rib extending inward from a top of the C-shaped holder.

A support frame includes a frame body and a sliding module. The frame body has a first guiding rail and a second guiding rail, wherein the first guiding rail is opposite to the second guiding rail and the first guiding rail is made of a magnetic induction material. The sliding module is slidably disposed on the frame body. The sliding module includes a plurality of first spherical bodies and a plurality of second spherical bodies, wherein the first spherical bodies rotatably abut against the first guiding rail, the second spherical bodies rotatably abut against the second guiding rail, and at least one of the first spherical bodies is a magnetic ball.
