And travelling gear and emery wheel on the power transmission shaft are separately mounted to, perforation is offered on the head capsule and is perforated together with described
The counterbore of axle arrangement, the counterbore are interspersed with resistance in the side of the inner chamber of the perforation away from the head capsule, the perforation
Grinding set, lock pin is interspersed with the wear-resistant sleeve, the button being fixedly connected with the lock pin, the lock pin are provided with the counterbore
On be also arranged with compression spring, one end of the compression spring is supported on the button, and the other end is supported in the counterbore
Bottom, side of the travelling gear away from the emery wheel offer the lock hole coordinated with the lock pin.
As a kind of improvement of the present utility model, annular groove is offered on the lock pin, rubber is arranged with the annular groove
Rubber ring, the rubber ring be arranged after external diameter be more than the wear-resistant sleeve internal diameter.
As a kind of improvement of the present utility model, the lock pin is divided into upper semisection and lower semisection by the annular groove, institute
The diameter for stating lower semisection is more than the external diameter of the rubber ring.
As a kind of improvement of the present utility model, the wear-resistant sleeve spiral is connected in the perforation.
As a kind of improvement of the present utility model, the lock hole has two or more, and each lock hole is with the transmission
Even cloth centered on the axis of gear.
Using above-mentioned technical proposal, the utility model has the advantages that：
1st, by setting lock pin and setting wear-resistant sleeve to obstruct lock pin and perforation so that head capsule is not easy to be worn by lock pin, really
Lock hole can be properly inserted all the time by protecting lock pin, easy to operate and be not easy to fail.
2nd, by setting rubber ring, dust during normal use can be not only avoided to enter by perforating in the inner chamber of head capsule,
Certain pretension effect can also be played, avoids button from being pressed by mistake.
