Description

   Compound sleeve   

The composite sleeve of the present invention refers to the technology applied in the field of hand tools. The main technology is to provide reliable pivoting and removal of screws, bolts, and nuts applied to automobile rims. It hurts the sleeve and the rim to protect the usability of the sleeve and the rim. It is a kind of highly progressive and practical.

Sleeve is a very practical part of hand tools. It can be combined with a wrench to provide users with access to, lock screws, nuts, bolts and other parts, especially those in the automotive field need to use, and the sleeve Another function is to provide users with screws, nuts, and bolts with deep lock positions. The sleeve can be inserted into the hole of the rim corresponding to the screw, nut, and bolt lock position for operation. It ’s smooth, so there will be oil stains on the rims to increase the smoothness when the rims turn, but when removing, turning screws, nuts, and bolts, the screws, nuts, and bolts can be reliably fixed. The wheel frame is firmly connected and reliable.

However, according to the above-mentioned method of using the sleeve, there are the following problems. Before explaining the problem, it will list the known technology first. Please refer to the Republic of China Patent Bulletin No. I468258 "composite sleeve", which mainly includes a body, A sleeve member and a bushing, the two ends of the body are respectively used for a driving tool to drive and drive a fixing member, the sleeve member is connected to one end of the body and has a peripheral surface, and the bushing is provided between the body and the sleeve The outer peripheral surface of the connector, the opposite two surfaces of the bushing have an outer surface and an inner surface, respectively, and the bushing can see the transmission part of the body and the outer peripheral surface of the bushing from the outer surface to the inner surface. The above list is one of the sleeves available on the market today. Although it is provided in combination with a wrench to lock, screw, nut, and bolt, carefully observe and refer to the twelfth to thirteenth drawings. Questions are as follows:

I. Dirty concealment: The outer surface of this sleeve is provided with a sleeve (5) according to transparency. The function of the sleeve (5) is to provide identification, and the user can still clearly identify a The color of the sleeve body (6) and a set of joints, but the oil in the car rim is easily attached to the bushing (5), causing the originally transparent part to become dirty and unrecognizable.

2. Dimensional problems: The sleeve is provided with a bushing (5), but the rim provides screws, nuts, and bolts. The size of the keyholes is specified according to the specifications. Most of the keyholes have a specific size. The hole diameter will be equal to the outer diameter of the socket body (6) to which one of the screws, nuts, and bolts is socketed. It can be said that the socket body (6) is close to the keyhole, especially for the use of special wheels It is obvious. However, when a bushing (5) is added, one end of the set of screws, nuts, and bolts will be restricted by the keyhole opening and cannot be inserted. However, if you change the sleeve that can be inserted into the keyhole, , Then it becomes impossible to work with screws, nuts, and bolts.

3. Use problem: According to the problem of the second point above, when the general user finds that the sleeve cannot be inserted into the lock hole for work, he has to remove the bushing (5) so that the sleeve body (6) can be inserted into the lock. Hole for operation, but after the user pulls the bushing (5) away, the original function of the bushing (5) is to protect both the rim and the sleeve body (6), which can avoid problems such as collision and friction between the surfaces. It occurs, but when the bushing (5) is pulled out, it cannot be protected, so that the bushing (5) is only reduced to the ordinary kit, and it has no protective effect at all.
