Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, a tubule cutter sleeve assembly 100 includes an outer sleeve 102 having a through cavity 101 formed at an axis, a tubule body 103 is inserted into the through cavity 101 in a fitting manner, a cutter head 104 is formed at one end of the tubule body 103, a circular truncated cone cavity 105 is formed at an end surface of the outer sleeve 102 facing away from the cutter head 104, a top surface diameter of the circular truncated cone cavity 105 is smaller than a bottom surface diameter thereof, a circular truncated cone body 106 is placed in the circular truncated cone cavity 105 in a fitting manner, a compression spring 107 is arranged between a bottom surface of the circular truncated cone body 106 and the bottom surface of the circular truncated cone cavity 105, the tubule body 103 is fitted with an axis cavity 108 formed by penetrating through the axis of the circular truncated cone body 106, a plurality of cavities 109 are formed by arranging and recessing the outer side wall of the circular truncated cone body 106 in a circumferential direction, the cavities 109 are communicated to the axis cavity 108, a ball 110 is arranged in each cavity 109, and a diameter at a connection position of the cavities 109 and the axis cavity 108 is smaller than a diameter of the ball 110. The capillary body 103 passes through the axial center of the compression spring 107. The top of the truncated cone 106 protrudes from the top surface of the outer sleeve 102. The circular truncated cone cavity 105 is formed in a cylindrical connecting member 111, and an end cap 112 is provided on the top surface of the cylindrical connecting member 111.
According to the technical scheme, when the thin tube body is inserted, the ball attached to the side wall of the thin tube body is driven to roll downwards, the circular truncated cone body moves downwards, the ball moves towards the outer side of the cavity, the compression spring presses downwards, and the thin tube body can conveniently move downwards; when moving to suitable position, compression spring kick-backs, returns the round platform body top to initial position, and the ball supports and holds in tubule body lateral wall this moment, and when the tool bit was used hard, the tubule body can't drive rebound with the ball, because the ball supports the firm subsides tubule body lateral wall after holding by cylindricality connecting piece this moment, the words of shifting up. When the operation is finished and the tubule body needs to be taken out, the tubule body only needs to be pulled out from the bottom and moves downwards or the circular truncated cone body is pressed downwards, and the ball is separated from the side wall of the tubule body after being pressed downwards and can be pulled out from the top.
