The above is the structure of each component of the combined structure of a lock provided by the present invention and a configuration description thereof.

The invention has the following effects:

First, the service life is increased. The handle of the horizontal lock device is used for a period of time, because the internal spring is tired, so that the handle of the horizontal lock device cannot be parallel to the floor, the present invention improves the above-mentioned deficiency by adding two strong and powerful springs. (The first spring 40A and the first The two springs 40B) are in the two sleeves (the first sleeve 30A and the second sleeve 30B) to achieve the purpose of strengthening the internal structure, and thereby enhancing the service life and smoothness.

Second, the push-type lock. Since the conventional horizontal lock device is locked by means of a knob, the user cannot clearly determine whether or not the lock is fixed in appearance, and the diameter of the knob is small, the operation is time consuming, and the operation is also quite unfavorable. Therefore, the present invention improves the above-mentioned deficiencies, and the pressing member 20 can be press-fitted in the first connecting member 11, and the user can easily determine whether or not the lock is locked by the appearance, and the pressing is determined according to whether the pressing member 20 is pressed or not. The member 20 is in a locked or unsecured state. When the pressing member 20 is in the non-locking state, the pressed end of the pressing member 20 is away from the through hole 511A, and when the pressing member 20 is in the locked state, the pressing member The pressed end of 20 is adjacent to the perforation 511A, and the manner of pressing is better and easier to operate than the conventional knob. In addition, the manner of the knob is often too close to the door frame when the force is applied, so that the back of the user's hand often rubs against the door frame. Therefore, the present invention can prevent the problem of contact or collision between the back of the hand and the door frame by pressing.

Third, it is a horizontal handle. The handle of the conventional horn lock device is spherical, which is quite troublesome and difficult to apply to an elderly person or a hand injured person who is not well stressed.
