Abstract

PURPOSE:To simplify the structure of a roller handle (conventional ratchet handle using a roller) and use more attachments such as sockets than before with one handle. CONSTITUTION:Grooves 2 are formed on the periphery of the hole of a handle section 1, a roller 3 is fitted to the grooves 3 with a holding metal 4 as a roller clutch, and an inner ring 8 integrated with a socket 5, a bit 6, or a hexagonal wrench 7 of various sizes is inserted into the inner bore of the roller 3 to form this work tool.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ratchet handle and a roller handle which have been conventionally used.

[0002]

2. Description of the Related Art In the conventional ratchet handle and roller handle, a ratchet handle is used to rotate a core (inner ring) between the handle and ratchet gear, and a socket or bit is connected to the core to exchange various sockets or bits. It has a structure that allows you to play with the mating connection. In addition, since the size of a pair of glasses cannot be exchanged with a single handle, it cannot be used for multiple sizes except for the two-sided ones with two types of glasses on the front and back. The same thing can be said about the roller handle, especially since the roller handle is characterized by having no play by itself, the play of the connection part with the socket has a great influence.

[0003]

[Problems to be Solved by the Invention]

(1) Reduce play by reducing the number of connected parts. (2) Glasses type handles can also be used by exchanging with 3 or more sizes. (3) Various operations can be performed with one handle. (4) Reduce the number of parts.

[0004]

Means for Solving the Problems A groove (2) is formed around a hole of a handle portion (1), and a roller (3) is attached to the groove with a holding metal fitting (4) to form a roller clutch. The inner ring (8) integrated with the socket (5) of various sizes, the bit (6), the hexagonal wrench (7), etc.

[0005]

[Action]

(1) The inner ring and the socket or bit are integrated so that the number of parts or points is reduced from the conventional one, and there is no gap between the inner ring (core) and the socket or bit, so that the connection part becomes a socket or bit. Only the screw can reduce the play between the handle and the screw part. In particular, since the one that uses the roller originally has no play on the handle itself, the feature of the roller handle comes to the point that the play is reduced by tightening the screw in the place. (2) In the case of the eyeglass type, the conventional type cannot be replaced with a different size with one handle, and it can be used only with one or two screws with both mouths, According to the present invention, only one handle is required even if there are three or more sizes. (3) Since the inner ring is directly connected to the handle, the conventional connection between the handle and the socket can be omitted and the height can be shortened, and a through hole can be opened in the center, so conventional sockets cannot be used. You can also tighten the nut that has a long screw.

[0006]

[Embodiment] V-groove around which a roller works as a clutch around the hole formed in the handle (1) Attach the handle using 4). Then, the inner ring (8) that acts as a latch is inserted into the inner diameter of the roller so that it can be easily inserted and removed, and a socket, a bit, a spectacle hole, etc. are provided integrally with the inner ring. If the inner ring is inserted into both of the two handle portions so that the inner ring can be inserted and connected, and according to claim 2, in addition to the features of the handle of Japanese Patent Application No. 5-7669, the operation is described. It will have such a characteristic. In addition, the two handle portions are driven by the swinging metal fittings (9) so as to reciprocate in opposite directions,
If the eccentric cam (10) for swinging the swing metal fitting is rotated by a motor, the application is made in Japanese Patent Application No. 6-11.
In addition to the feature of 0595, it has the feature described in the operation. The clutch action can be switched to the left and right by forming a groove and adding a switch fitting that switches the roller to the left and right. With this, in the case of only one direction, you have to change the rotation by replacing the socket etc. on the front and back of the handle,
There is no need for that.

[0007]

Although the effects have been described in terms of the operation and the embodiment, in addition to the above, depending on the method of operation, the socket type handle or the spectacle type handle, particularly the spectacle type handle, has a screw It was necessary to use a large number of handles, such as different handles depending on the size, and different handles for the long type, but with the handle of the present invention,
The number of handles to be used can be greatly reduced since it can be used with ordinary handles from several types of eyeglass type, short size and long type. In particular, in the case of a power work tool using a motor, the cost of the handle is high, and the effect is very large.
