In a specific application, the guide groove 131 of the telescopic tube 130 slides in cooperation with the guide bar 123 of the support tube 120, so that the telescopic tube 130 stretches on the support tube 120 along the first axial direction, wherein the support tube 120 comprises a deformation portion 121, a tube body 122 and the guide bar 123, the guide bar 123 is partially arranged on the tube body 122, and is partially arranged on the deformation portion 121, when the trigger sleeve 110 is operated, the deformation portion 121 can be deformed, at the moment, the shrinkage groove 1211 of the deformation portion 121 is shrunk and deformed, so that the guide bar 123 fixed on the deformation portion 121 is deformed, the relative position relationship between the guide bar 123 on the tube body 122 is unchanged, and therefore, dislocation is generated between the guide bar 123 on the tube body 122 and the guide bar 123 of the deformation portion 121, the guide bar 123 is abutted on the inner side wall of the guide groove 131, the abutting pressure between the guide bar 123 and the guide groove 131 is increased, and the static friction force between the telescopic tube 130 and the support tube 120 is increased, so that the telescopic tube 130 is locked on the support tube 120, and the stability of the telescopic tube 100 is further improved.
