Both ends of the locking rod 4 can be inserted into the corresponding locking rod grooves 35, thereby locking the blade holder 32 in the tool mount 2. Alternatively, two locking lever pushing buttons are provided on the locking lever 4, which are exposed outside the body, and a tip portion 42 is formed at each end of the locking lever 4, so that when the positions of the locking lever groove 35 and the locking groove 12 on the blade holder 32 are not completely matched, the locking lever 4 can still be inserted into the locking lever groove 35, and can also be matched with the inclined surface 36 of the blade holder 32 in the semi-ejecting state, so as to conveniently push the blade holder 32 out of the tool mounting seat 2.

Since the lock lever 4 is provided between the two tool mounts 2, only the blade holder 32 at one end can be locked, and the blade holder 32 that is not locked is ejected a distance and is in a half-ejected state, in the half-ejected state, the blade holder 32 can be pressed into the tool mount 2 again, and the lock lever 4 is inserted into the lock lever groove 35 to form an inserted state (i.e., a locked state), so that the blade holders 32 at both ends can be switched easily.

As shown in fig. 3, the blade holders 32 at both ends can be quickly switched between the insertion state (use state) and the half-eject state (seating state), and only one is in the insertion state. When the direction of use is changed, only the blade holder 32 at the other end needs to be pressed in and the locking lever 4 needs to be inserted, and the blade holder 32 used originally can be automatically ejected (half-ejected state) because the locking lever 4 is pulled out.

The blade holder 32 can thus slide along the transverse positioning edge 23 in the tool mount 2. Optionally, a lateral positioning slot 37 is provided in at least one surface of the blade holder 32 to improve stability of the blade holder 32 as it slides within the tool mount 2, preventing the blade holder 32 from shifting.

Optionally, the other end of the blade holder 32 is provided with a grasping portion 38, the side of the blade holder is provided with at least two edges 39, and the grasping portion 38 and the at least two edges 39 enclose a transverse positioning slot 37; the number of the transverse positioning ribs 23 is at least two, and when the transverse positioning ribs 23 are mutually clamped with the transverse positioning grooves 37, the transverse positioning ribs 23 are abutted against the side walls of the transverse positioning grooves 37. The gripping portion 38 is remote from the blade edge of the knife 3 to facilitate gripping of the blade holder 32 by a user. It should be noted that the position of the edge 39 matches the position of the lateral positioning edge 23, the number of the edge 39 may be more than two, and the number of the lateral positioning edges 23 is increased accordingly so that the edge 39 matches the lateral positioning edges 23. In particular, a rim 39 may be provided on both sides of the blade holder 32, one end of the rim 39 being connected to the gripping portion 38 so as to enclose the lateral positioning slot 37. Alternatively, one end of the elastic member 342 is connected to the grasping portion 38 of the blade holder 32, and the other end is connected to the stopper piece 341.

Alternatively, the locking lever 4 slides in a direction perpendicular to the lateral positioning ridge 23, and the lateral positioning groove 37 communicates with the locking lever groove 35. As shown in fig. 2, when the locking lever 4 is inserted into the lever groove 35, the locking lever 4 may form a cross lock with the lateral positioning rib 23 to limit the sliding position of the locking lever 4 in the positioning groove 33.
