SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem of inconvenient process of disassembling the existing expansion screw, and provides an expansion screw disassembling tool.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides an expansion screw extracting tool, it is applicable to on some screw rod tail ends set up the expansion screw of screw hole, its characterized in that, it includes the body of rod, fixedly on the body of rod be equipped with the stopper, still slide on the body of rod and be equipped with the piece of strikeing, the tip of the body of rod is equipped with the connector, is connected with the link up piece through adapting unit on the connector, the terminal surface an organic whole of link up piece dorsad the body of rod is equipped with the screw thread outer pole, the screw thread outer pole can cooperate with the screw hole of expansion screw. The connecting piece can be of various types and respectively corresponds to expansion screws of different types, the connecting piece is disassembled or fastened through the connecting component to complete separation or butt joint, in the using process, a threaded outer rod on the connecting piece is screwed into a threaded hole of the expansion screw, then the front end of the rod body is held by one hand, the knocking block is held by the other hand, the limiting block is hammered for multiple times towards the rear side by the knocking block, and the whole rod body is pulled out backwards together with the connecting piece and the expansion screw through the impact force in the backward direction provided by the limiting block.

In the above-mentioned expansion screw extracting tool, the stopper have two both ends that are located the body of rod respectively, the connector also has two both ends tip that are located the body of rod respectively. After the connectors are arranged on two sides of the tool, the connecting pieces can be installed on two sides of the tool, so that the tool can be used for detaching two kinds of expansion screws on the premise of not replacing the connecting pieces, and the square orientation of the rod body can be adjusted in the using process.

In foretell expansion screw extracting tool, adapting unit including set firmly the square bar of body of rod tip and set up the square hole on linking up the piece, the square bar can insert the square hole in, the side in square bar and square hole runs through and has seted up a plurality of jacks, can dismantle in the jack and establish the fastener.

In the above-mentioned expansion screw removing tool, the connecting member includes a fixing screw fixed to the end of the rod body and a fixing screw hole formed in the connecting member.

In the expansion screw dismounting tool, the edge of the knocking block is chamfered with an arc angle.

Compared with the prior art, the dismounting tool can conveniently dismount the expansion screw, and the tool structure is simple.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

This inflation screw extracting tool is applicable to on some screw rod tail end set screw hole's the inflation screw, it includes the body of rod 1, the fixed stopper 2 that is equipped with on the body of rod 1, it strikes piece 3 still to slide on the body of rod 1, the tip of the body of rod 1 is equipped with connector 4, be connected with linking piece 5 through adapting unit on the connector 4, linking piece 5 is equipped with the outer pole of screw thread in the body of rod 1's the terminal surface an organic whole, the outer pole of screw thread can cooperate with the screw hole of inflation screw, strike piece 3 and be in between stopper 2 and connector 4, strike 3 edges of piece and fall the arc angle.

The connecting piece 5 can be of various types and respectively corresponds to expansion screws of different types, the connecting piece is disassembled or fastened to complete separation or butt joint, in the using process, an outer threaded rod on the connecting piece 5 is screwed into a threaded hole of the expansion screw, then the front end of the rod body 1 is held by one hand, the knocking block 3 is held by the other hand, the limiting block 2 is hammered for multiple times towards the rear side by the knocking block 3, and the whole rod body 1 is pulled out backwards together with the connecting piece 5 and the expansion screws through the impact force in the backward direction provided by the limiting block 2.

Stopper 2 has two both ends that are in the body of rod 1 respectively, and connector 4 also has two both ends tip that are in the body of rod 1 respectively, and both sides have all set up connector 4 after, can all install linking piece 5 on both sides, and this instrument can also demolish two kinds of inflation screws like this under the prerequisite of not changing linking piece 5, as long as in the use the square orientation of adjustment body of rod 1 can.

The connecting part can be a square bar fixedly arranged at the end part of the rod body 1 and a square hole arranged on the connecting piece 5, the square bar can be inserted into the square hole, a plurality of jacks 6 are formed in the side surfaces of the square bar and the square hole in a penetrating manner, and fasteners can be detachably arranged in the jacks 6.
