DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1-3 As shown, a safety emergency stop switch comprises a terminal block 1, on which a terminal block 2 and a transmission shaft 3 are arranged, the terminal block 2 is symmetrically embedded below the terminal block 1, the outer side of the terminal block 2 is integrally connected with a fixed contact piece 4, the transmission shaft 3 is nested in the middle of the terminal block 1, and a first spring 5 is placed between the bottom of the transmission shaft 3 and the inner wall of the terminal block 1, and a movable contact piece 6 is integrally connected to the upper end of the transmission shaft 3, the top of the terminal block 1 is connected with a driving seat 7 through a thread, and a driving seat 8 and a driving connecting rod 9 are arranged on the driving seat 7, the driving seat 8 is placed on the top of the driving seat 7, and the driving connecting rod 9 is placed above the inside of the driving seat 7, the bottom of the transmission seat 8 is connected with a driving buckle coupling 10, and the inside of the driving buckle coupling 10 is symmetrically provided with an emergency stop driving buckle 11, and a second spring 12 is placed between the inner sides of the emergency stop driving buckle 11, and the bottom of the driving buckle coupling 10 is connected with an upper transmission shaft 13, and the position of the upper transmission shaft 13 and the transmission shaft 3 is symmetrical.

[0015] Specific usage: Under normal conditions, the movable contact piece 6 is tightly fitted with the fixed contact piece 4 under the drive of the first spring 5; when an emergency stop is required, the transmission seat 8 is pressed to drive the driving buckle coupling shaft 10 to move downward, and the driving buckle coupling shaft 10 moves downward and drives the emergency stop driving buckle 11 to move inward under the action of the driving connecting rod 9. At the same time, the driving buckle coupling shaft 10 moves downward and drives the upper transmission shaft 13 to move downward, and the upper transmission shaft 13 moves downward and drives the transmission shaft 3 to move downward, and the transmission shaft 3 moves downward and drives the movable contact piece 6 to move downward and disconnect from the fixed contact piece 4.
