Description

Tool head post

This creation is related to the post structure, especially the post of a tool head.

Please refer to the Republic of China No. M313575 patent, an elongated tool post comprising a post and a grip. The post has a first end and a second end, the first end is provided with a connecting end for connecting the tool, and the second end of the post is formed with a plug end connected to the power tool, The post forms a shaft segment between the ends. The grip member is pivotally disposed on the shaft segment of the post and can be in a relative rotational relationship.

The above-mentioned conventional elongated tool post, the post can be connected to different tool heads for locking use, but during the locking operation, since the tool head is inserted into a lock, the lock is easily detached, thus causing The locking work is interrupted, and the tool head must be reinserted into the lock, which causes inconvenience in the locking operation, and the elongated tool post still has room for improvement.

The main purpose of this creation is to provide a tool head post for the purpose of locking work.

According to the present invention, a tool head post includes a rod body and a movable sleeve. One end of the rod body is provided with a joint member, the joint member is elongated, and the joint member is recessed from the outer side to form a chamber for inserting a tool head, and the tool head is combined with the joint member, the joint The outer peripheral wall of the piece is recessed to form a first ring groove, and a first C-shaped button is fastened to the first A ring groove, the other end of the rod forms a driving segment. One of the movable sleeves is provided with a magnetic ring, and the movable sleeve is axially movably fitted to the outer edge of the joint member, and the magnetic ring can resist one end of the joint member of the rod body, and the movable sleeve is The inner wall surface is recessed to form a limiting slot, and when the movable sleeve is displaced away from the driving section by a predetermined distance, the first C-shaped buckle buckles the limiting slot, so that the movable sleeve is limited to The joint member, in turn, prevents the movable sleeve from coming off the joint member.

Thereby, the magnetic ring of the movable sleeve of the present invention sucks a screw lock member, and at the same time, the driving groove of a screw lock member is inserted by the driving end of the tool head, and the tool head drives the screw lock member to perform the screw lock member. During the locking operation, the tool head can be prevented from separating from the screw lock to ensure the locking operation.

In order to explain in detail the technical features of the present invention, the following preferred embodiments are described below with reference to the following:

Referring to FIG. 1 to FIG. 6 , a tool post 100 of the first preferred embodiment of the present invention is mainly composed of a rod 10 , a holding tube 20 and a movable sleeve 30 .

The rod body 10 is provided with a joint member 11 at one end. As shown in FIG. 2, the joint member 11 is elongated. The joint member 11 is recessed from the outside to the inside to form a chamber 111 for a tool head 40. As shown in FIG. 4, the tool head 40 is coupled to the joint member 11. The outer peripheral wall of the joint member 11 is recessed to form a first annular groove 112, and a first C-shaped buckle 12 is fastened to the first ring. The slot 112, the other end of the rod 10 forms a driving section 14. In the first embodiment, the portion of the rod body 10 between the driving portion 14 and the joint member 11 is defined as a limiting portion 16, and the diameter of the limiting portion 16 is smaller than the diameter of the joint member 11, such as As shown in Fig. 2, the limiting section 16 forms a stepped shape with the joint member 11. In addition, a second C-shaped buckle 18 is further recessed to form a second annular groove 161 near one end of the driving segment 14 , and the second C-shaped buckle 18 is fastened to the joint member 11 , and Located in the second ring groove 161.

The holding tube 20 is sleeved on the outer edge of the limiting portion 16 of the rod body 10. As shown in FIG. 2, the holding tube 20 is limited to the limiting portion 16, when the driving portion 14 of the rod body 10 is The limit segment 16 is rotatable relative to the grip tube 20 when it is rotated. In the first embodiment, the two ends of the holding tube 20 are respectively restricted between the one end of the connecting member 11 and the second C-shaped buckle 18, as shown in FIG.

One end of the movable sleeve 30 is provided with a magnetic ring 31. As shown in FIG. 2, the movable sleeve 30 is axially movably fitted to the outer edge of the joint member 11, and the magnetic ring 31 can resist the rod. One end of the joint member 11 of the body 10, the inner wall surface of the movable sleeve 30 is concavely formed to form a limiting groove 32. When the movable sleeve 30 is displaced a predetermined distance away from the driving portion 14, the first C-shaped buckle 12 will latch the limiting slot 32, and the movable sleeve 30 is restrained by the joint member 11, so that the movable sleeve 30 cannot be disengaged from the joint member 11, as shown in Fig. 6. In the first embodiment, the inner peripheral wall of one end of the movable sleeve 30 is recessed to form a coupling groove 34, and the magnetic ring 31 is located at the coupling groove 34, as shown in FIG. In addition, the limiting groove 32 of the movable sleeve 30 has a cross-sectional shape of a hook shape.

The structure of the first preferred embodiment of the present invention has been described above, and the state of use of the first preferred embodiment of the present invention will be described next.

Referring to Figures 3 through 6, the fixed end 41 of the tool head 40 is placed into the chamber 111 of the joint member 11, as shown in Figure 4. Then, when the hand pulls the movable sleeve 30 away from the driving segment 14 by a predetermined distance, the first C-shaped buckle 12 will catch the limiting slot 32, and one part of the movable sleeve 30 will The connector member 11 is protruded, and the magnetic ring 31 of the movable sleeve 30 sucks a screw member 50, and at the same time, the driving groove 51 of the screw member 50 is inserted into the driving end 42 of the tool head 40, as in the fifth. The figure shows. Then, the screw lock 50 is inserted into a locked object 60. When the tool head 40 drives the screw lock 50 to perform a locking operation, the tool head 40 can be prevented from being separated from the screw lock 50 to ensure the lock. The solid work is carried out as shown in Figure 6. Finally, the driving section 14 of the rod body 10 is clamped by a power tool (not shown). When the rod body 10 is driven to rotate, the hand of the user can be directly gripped on the holding tube 20, so that When the rod body 10 is driven and driven, the twist lock can be stably applied without the disadvantage of shaking or yaw. In this way, work efficiency can be improved.

It can be seen from the above that the achievable effect of the present invention is that the prior art is concerned that the insertion of the tool head into the locking screw is easy to disengage, and therefore, the locking operation is interrupted. The magnetic ring 31 of the movable sleeve 30 of the present invention attracts the screw member 50, and at the same time, the driving groove 51 of the screw member 50 is inserted by the driving end 42 of the tool head 40, when the tool head 40 is driven. When the screw lock 50 is locked, the tool head 40 can be prevented from being separated from the screw lock 50 to ensure the locking work.

Referring to FIG. 7, a second preferred embodiment of the present invention provides a tool post post 200, which is mainly similar to the first embodiment described above, except that:

The holder 200 of the tool head may also be provided with the holding tube and the limiting portion. The only difference is that the driving section 14 of the rod body 10 is clamped by the power tool (not shown) when the rod body 10 is driven. When rotating, the user's hand cannot be directly gripped on the holding tube, and the rod body 10 is stabilized to perform a twisting and biasing force. In the second embodiment, a fixing member A is disposed in the chamber 111 of the rod body 10. The fixing member A is a magnet, and the magnet can magnetically attract the fixed end of the tool head (shown in FIG. 4). The fixing member A can also be a C-shaped buckle (not shown), and the C-shaped buckle can be fastened around the tool head.

The rest of the structure of the second preferred embodiment of the present invention is the same as the first preferred embodiment, and will not be described again.
