When at a position where the corresponding roller guide slot communicates with the positioning hole, the roller set protrudes to the positioning hole to be in rolling contact with at least one side of the insert.

A hand tool includes a handle and a connection portion which is connected to the handle. The handle is a hollow handle and has a space defined therein. The connection portion includes a slit. A blade has a body and a toothed portion which is inserted into the slit of the connection portion when the handle and the connection portion are connected to each other by way of blow molding. A cooling material is located in the space of the handle. The temperature of the cooling material is the same as the temperature of the handle and the connection portion during blow molding. The cooling material contacts the inside of the handle to cool down the handle. The cooling material performing as a weight in the handle 2.

A method for manufacturing a handle includes manufacturing a surface portion for the handle, arranging the surface portion having a uniform thickness in a mould to contact a surface of the mould and to cover cavities which are provided in the surface in a predetermined pattern, pressing those parts of the surface portion that cover the cavities into the cavities with a mass that is introduced into the mould, and removing the handle from the mould once the mass has cured to form a rigid body which is at least partly covered by the surface portion from which protrusions arranged in the predetermined pattern protrude.

A tool and a coating method thereof are provided. The tool includes: a main body including connected head and grip portions, an end of the grip portion being a tail portion; a first coating layer coated on the main body; a second coating layer, coated on the first coating layer continuously corresponding to the grip portion and protrudingly formed with a pattern portion, formed with a first flange formed radially corresponding to the tail portion; a third coating layer, at least coated on the second coating layer, the pattern portion being at least partially exposed. The coating method includes the following steps of: manufacturing a main body into a first product having the first coating layer; manufacturing the first product into a second product having the second coating layer; and manufacturing the second product into a tool having the third coating layer.

A coating structure for forming a tool comprises a tool body and an outer coating layer. The tool body includes at least one base plate, an upper limiting plate, a lower limiting plate, a ratchet driving member, a stirring member, and at least one pin. The base plate has a handle portion and a driving portion which is connected with one end of the handle portion. An accommodating groove is arranged at the driving portion and received the ratchet driving member and the stirring member. The upper and lower limiting plates are stacked on the upper and lower surfaces of the driving portion respectively. The outer coating layer is covered the outer surfaces of the upper and lower limiting surfaces and the base plate for fastened so as to prevent the outer coating layer from sliding while in operation. The operating quality is efficiently increased and the cost is saved.

The present invention relates to a hand tool, comprising a tool member, of a first material, an elongated shaft, of a second material and a connecting member, of a third material comprising plastic. The elongated shaft further comprises a handle portion in a first end and an insert portion in a second end. The hand tool further comprises a sealing ring arranged to surround the insert portion to prevent leakage of the third material during manufacturing. A manufacturing method for such a hand tool is also presented, said method comprising arranging a sealing ring around an insert portion, arranging the insert portion and a tool member in a mold, injecting material comprising plastic in a cavity space so as to form a connecting member and removing the hand tool from the mold.

An anchoring method of anchoring an anchoring element in a construction object is provided, where a surface of which object has at least one of pores in a surface, structures in a surface (such as an arrangement of ridges with undercut), a inhomogeneous characteristic with makes the penetration of a surface by a liquid under pressure possible, thereby creating pores filed by the liquid underneath the surface, and of a cavity. The method includes the steps of: providing a first element and a second element, the first element comprising a thermoplastic material; positioning the first element in a vicinity of said surface and/or of said cavity, respectively, and positioning the second element in contact with the first element; and causing a third element to vibrate while loading the first element with a force, thereby applying mechanical vibrations to the first element, and simultaneously loading the first element with a counter-force by the second element.

The invention relates to a tool holding fixture (1) for rotationally driven tools (2), said tool holding fixture comprising a rotationally symmetrical holding body (3) which has a front clamping region (4) having a receiving opening (5) for a tool shank (6) of the tool (2), and a rear holding region (7) to be held in a work spindle of a machine tool. In order to achieve a reduced mass, a lower mass moment of inertia and at the same time high stiffness, a sleeve (11), made of a fiber reinforced plastic, is disposed in at least the front clamping region (4).

A coating structure for forming a tool comprises a tool body and an outer coating layer. The tool body includes at least one base plate, an upper limiting plate, a lower limiting plate, a ratchet driving member, a stirring member, and at least one pin. The base plate has a handle portion and a driving portion which is connected with one end of the handle portion. An accommodating groove is arranged at the driving portion and received the ratchet driving member and the stirring member. The upper and lower limiting plates are stacked on the upper and lower surfaces of the driving portion respectively. The outer coating layer is covered the outer surfaces of the upper and lower limiting surfaces and the base plate for fastened so as to prevent the outer coating layer from sliding while in operation. The operating quality is efficiently increased and the cost is saved.

The disclosure addresses wrenches having a portion thereof including carbon fibers. Example wrenches may have a handle portion comprising the carbon fibers; which in some cases can be formed as a part of a composite laminate structure of at least a portion of the handle. Example wrenches will often include an insert portion for engaging a bolt, nut, or similar structure. In most cases, the insert will be formed of a relatively hardened material, such as a metal, or a metal-containing, material.
