The utility model is further provided that the connecting groove is annular, the connecting groove is coaxially arranged with the screw rod part, the nut part is provided with a communicating groove which is communicated with the connecting groove and the inner side of the nut part, and the positioning piece can be connected in the connecting groove and the communicating groove in an adapting way.
The utility model further provides an annular fixing ring which is sleeved on the screw rod part, the fixing ring can be magnetically attracted and fixed with the nut part, and the positioning piece is positioned between the nut part and the fixing ring.
The utility model is further arranged that the positioning groove is arranged through two axial ends of the screw rod part.
By adopting the technical scheme, the utility model has the beneficial effects that:
(1) The nut can move on the screw rod to adjust the length of the screw rod used as the screw, thus achieving the effect of adjusting and changing the length of the screw.
(2) The screw cap is in threaded connection with the screw rod, so that the screw cap is convenient to move and adjust, and the screw cap and the screw rod are circumferentially fixed through the connecting piece, so that a screw structure with stable structure is formed.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model is illustrated below with reference to fig. 1-4:
Example 1: the utility model provides a screw, including screw rod portion 1 and nut portion 2, screw rod portion 1 and nut portion 2 form and can dismantle the connection, be equipped with on the nut portion 2 with screw rod portion 1 threaded connection's screw hole 3 for nut portion 2 can carry out position control at screw rod portion 1, so adjust the length of screw rod portion 1 as the part that the screw rod portion used, be equipped with constant head tank 4 along its axial direction on the lateral wall of screw rod portion 1, constant head tank 4 runs through screw rod portion 1's axial both ends setting, constant head tank 4 is equipped with two, two constant head tanks 4 set up at screw rod portion 1's circumference interval.
Still include setting element 5, be equipped with spread groove 6 on the axial terminal surface of nut part 2, spread groove 6 is the annular, spread groove 6 and the coaxial setting of screw rod part 1, be equipped with the intercommunication spread groove 6 and the inboard intercommunication groove 7 of nut part 2 on the nut part 2, intercommunication groove 7 corresponds the setting with constant head tank 4, but setting element 5 adaptation is connected in spread groove 6 and intercommunication groove 7, setting element 5 includes annular go-between 51, go-between 51 adaptation is connected in spread groove 6, be equipped with the locating strip 52 of bar on the inside wall of go-between 51, the locating strip 52 adaptation is connected in intercommunication groove 7, the tip of locating strip 52 stretches into in the constant head tank 4, make screw rod part 1 and nut part 2 fixed connection in circumferencial direction in constant head tank 4 and spread groove 6, setting element 5 connection.
