The other end of the rod 4 is inserted into the first hole 21, and at this time, the rod 4 can extend and retract along the axial direction of the first hole 21, so that the batch head 3 can float in the axial direction. An elastic body is arranged between the rod body 4 and the bottom of the first hole 21, and the elastic body can apply axial force on the rod body 4, so that the rod body 4 can elastically stretch and contract in the axial direction in the first hole 21.

As a specific implementation manner of this embodiment, in this embodiment, a convex portion 41 is provided on the circumferential side wall of the rod 4, and the convex portion 41 may be a protrusion provided on the circumferential side wall of the rod 4 or a ring surrounding the rod 4. The block body 2 is provided with a blocking piece 7, the blocking piece 7 covers the hole opening of the first hole 21, the rod body 4 penetrates through the blocking piece 7, an installation cavity is formed between the blocking piece 7 and the hole wall and the hole bottom of the first hole 21, and the convex part 41 is arranged in the installation cavity, so that the axial moving distance of the rod body 4 is limited, the rod body 4 is prevented from coming out of the first hole 21 without any reason, and the stability is enhanced. The elastic body is disposed between the protrusion 41 and the bottom of the first hole 21, so that the elastic body exerts an axial elastic force on the protrusion 41 to drive the rod 4 to elastically expand and contract along the axial direction of the first hole 21.

More specifically, the elastic body is a spring 6, the spring 6 is sleeved outside the rod 4, and two ends of the spring 6 are respectively abutted against the protrusion 41 and the bottom of the first hole 21, and preferably, the spring 6 is in a compressed state after being installed, so that two ends of the spring 6 can respectively exert elastic force between the bottom of the first hole 21 and the protrusion 41, when the rod 4/the bit 3 is subjected to an axial force in the first hole 21, the rod 4 is pressed into the first hole 21, the protrusion 41 compresses the spring 6, and when the pressure is removed, the spring 6 drives the rod 4 to move out of the first hole 21. It should be noted that, in the natural state, the top end of the protrusion 41 is in contact with the bottom end of the stopper. As another embodiment of this embodiment, the elastic body may be a bladder that is inflated or flushed with liquid. In addition, the rod 4 may be a hollow structure instead.

As a more specific embodiment of the present embodiment, the blocking member 7 in the present embodiment may be configured to pass through the rod 4 and block the aperture of the first hole 21. Preferably, the blocking member 7 includes a first plate 71 and a second plate 72, the first plate 71 and the second plate 72 are respectively provided with a first groove 711 and a second groove 721, the first plate 71 and the second plate 72 are respectively detachably and fixedly connected to the other end surface of the block 2 through screws, the first groove 711 and the second groove 721 are spliced to form a second hole 73, the second hole 73 is adapted to the rod 4, the rod 4 can be inserted into the second hole 73, the second hole 73 is coaxial with the first hole 21, for example, the diameter of the second hole 73 is smaller than that of the first hole 21, and the outer diameter of the rod 4 is equal to that of the second hole 73. Through this kind of structure, at first peg graft the body of rod 4 in first hole 21, install the other end tip at the body of rod 4 respectively with first plate body 71 and second plate body 72 afterwards, body of rod 4 is then embraced to first plate body 71 and second plate body 72 this moment, the pore wall of second hole 73 can carry out preliminary radial positioning to the body of rod 4 this moment, but because second hole 73 is located the middle part of the body of rod 4, so the body of rod 4 still has askew possibility this moment, limit structure through among embodiment 1, then can avoid the slope of the body of rod 4. The first plate 71 and the second plate 72 in this embodiment are actually a flange. The blocking member 7 of this structure is easy to install.

As a preferred embodiment of the present invention, the second hole 73 in the present embodiment is a square hole, and the section of the rod 4 inserted into the second hole 73 is a square adapted to the square hole. By utilizing the mutual interference between the outer wall of the square block and the wall of the square hole, the rod body 4 can only stretch and move along the axial direction of the second hole 73/the first hole 21 and cannot rotate, and the stability is further enhanced.

As a best implementation manner of this embodiment, the limiting structure in this embodiment is an insertion block 5 disposed at the other end of the rod 4, an insertion hole 23 is disposed at the bottom of the first hole 21, the insertion hole 23 is adapted to the insertion block 5, the insertion block 5 may be a cylindrical, square or regular polygonal cylinder, the insertion block 5 is inserted into the insertion hole 23, an outer wall of the insertion block 5 is tightly attached to an inner wall of the insertion hole 23, and thus, the other end of the rod 4 is fixed relative to the radial position of the block 2, so as to radially limit the rod 4. The structure has the advantages of simple structure and convenient manufacture. In addition, this limit structure and above-mentioned second hole 73 and the mutual effect cooperation between the body of rod 4 carry out radial spacing, and the effect is better to the body of rod 4. And the end part of the other end of the rod body 4 and the middle part of the rod body 4 are limited radially at the same time, so that the rod body 4 is prevented from tilting, and the screwdriver head 3 is prevented from tilting.
